Cause of discoloration ? Smoking, coffee, tea, drugs, aging, staining food (wine, blueberry, etc) genetics. 

Kindly consult a dentist in person for further suggestion. We need more investigations to decide upon treatment. You may need deep cleaning along with whitening (bleaching) procedures and / or artificial enamel filling and / or capping. Advance procedures can be done with laser. 

Use Snowdent tooth paste for whitening until then. Apply SNOWDENT paste on the teeth. Wait for 10 to 15 min .Then brush your teeth with the same paste. Applying it overnight for better results.
